DANIEL II. TWAITS, OF CHICAGO, ILLINOIS.

GREASE-CUP CAP.

Application led December 22, 1913.

To aZZ 'whom t may concern:

Be. it known that I, DANinL H. Twairs, a citizen of the United States,residing at Chicago, in the county of Cook and Stato of illinois` haveinvented a certain new and which screws onto another and a spring detentis provided for preventing one of the members becoming inadvertentlyremoved from the other.

The object is to provide an o'liicient dctent spring which may becheaply manufactured and readily secured to one of the members of thecup.

My invention is hereinafter fully described and the essentialcharacteristics set forth in the claims.

Figure 1 is a central vertical section of the grease cup showing myspring mounted therein; Fig. 2 is a central vertical section of the sametaken at right angles to the plane of F ig. 1; Fig. 3 is a horizontalsection taken substantially on the line 3 3 of Fig. 1; Fig. 4 is aperspective view of the detent spring by itself.

In the drawings, 10 indicates a grease cup body having an enlargedportion forming a head provided on its periphery with threads whichcoperate with the threads 12 formed on the interior of the cap 13. Theinterior of the body 10 may be provided with vertical grooves or may bemade angular as shown at 15 which provides means for engaging the detentspring 16 to prevent the cap inadvertently turning and thereby becomingdisplaced or lost.

The spring 1G comprises two legs 1S joined at their upper ends at 20,forming in effect a substantially U-shaped spring. At their lower endsthe legs are rounded outwardly and then inwardly as at 21 and arepreferably provided with small humps 22 adapted to engage the grooves orangular portions of the body 10. At the connecting portion 20 areprovided two legs 24, preferably integral with this portion, which eX-tend outwardly and then upwardly from the connecting portion and arepassed through the top of the cap and upset as at Q5 to securely holdthe spring in place.

Carried by the side of the legs 18 is a wing Specification oi LettersPatent.

member 2G extending in a U-shape around the opposite leg and ending at28 adjacent the leg carrying it. rihese wing members are preferably madeintegral with the legs carrying them but l do not wish to be limited tothis construction as they may be secured thereto in any convenientmanner. Each wing member embraces the sides of the opposite leg whichprevents one leg being bent out of its normal relation with the other incase the ends 2l of the spring should become caught or for-some reasonshould be held against turning, thereby tending to cause the spring tobe bent or distorted by the turning of the cap.

This spring may be readily bent into the shape shown, from a blank whichmay be conveniently stamped from a piece of sheet metal, and accordinglyit will be seen that it may be very cheaply manufactured.

Having thus described my invention, what I claim is:

1. The combination ofqa grease cup comprising a cap member and a bodymember coperating therewith, and a substantially U-shaped spring securedto one of the members, and means carried by one of the legs of thespring for preventing distortion of the spring, said body member havingmeans engaging the free ends of said spring.

2. The combination of a grease cup comprising a cap and a body portionand a substantially U-shaped spring secured at the connecting portionthereof to one of said members and engaging the other member at the freeends of the spring and having means carried by one of the sides of the Uof the spring and engaging the other side thereof. said body memberhaving means engaging the free ends of said spring.

3. The combination of a grease cup comprising a cap member and a bodymember secured thereto, and a substantially U-shaped spring having twolegs and a connecting portion secured to one of the members at theconnection between the legs of the spring, and means carried by one ofthe legs and embracing the other leg, said body member having meansengaging the free ends of said spring.

4. In a grease cup, the combination of a body portion and a cap threadedthereon, a spring having two legs and a connecting portion forming a U,and means connecting the two legs and carried by them respectively forpreventing distortion of the spring, said the cap, and means carried byone oi the legs and extending around the other limiting the movement ofthe legs in one direction, said body portion having a non-circularportion engaging the free ends of the spring.

6. The combination of a grease cup comprising a body member and a capmember threaded on the body member, of a spring Yformed olE a flat striphaving two legs secured together at one end and Al'laring outwardly atthe free ends, means for securing said spring at the connected end ofthe legs to the cap, and means carried by one leg of the spring engagingthe other leg, said body,

portion having a non-circular portion engaging the free ends of thespring.

7. rlhe combination of a grease cup comprising a body member and a capmember threaded thereto, a spring having two legs and a connectingportion, means carried by the connecting portion for securing the springto the cap, and means carried by one of the legs and engaging the otherallowing the legs to move toward and away from each other but tending toprevent one leg moving laterally with relation to the other, said bodyportion having a non-circular portion engaging the free ends of thespring.

8. In a grease cup, the combination of a body portion and a cap threadedthereon and a spring having two legs and a connecting portion forming aU, means carried by one of the legs having two parallel portionsengaging opposite sides of the other leg, and means for securing thespring to the cap, said body portion having a non-circular portionengaging the free ends of the spring.

9. In a grease cup, the combination of a body portion and a cap portionthreaded thereon and a spring formed oi a iiat strip having two legs anda connecting portion forming a U, said legs flaring outwardly at theirfree ends, and means carried by the connecting portion for engaging thecap,

and a wing secured by one of the legs and extending around the other,said wing having parallel sides engaging the sides of said last namedleg while allowing the legs to be .moved toward and away from eachother, but limiting their outward movement, said body portion having anon-circular portion engaging the free ends of the spring.

l0. The combination of a grease cup comprising a cap member and bodymember, one screwing onto the other, a substantially U- shaped springformed oi a vflat strip, means securing the spring at its connectingportion to one of the members, the 'free ends being adapted to engagethe other member, a projeetion carried by one leg of the spring andslidably engaging the other preventing excessive lateral movement of oneleg with relation to the other.

ll. In a grease cup, the combination of a body and a cap threadedthereon and having an opening in its top, a spring having two legs and aconnecting portion, means extending' from the connecting portion throughthe opening in the cap and being upset at the top of the cap to securethe spring to the cap, said legs being iiared outwardly at their lowerends, and projections pressed from the flaring portions and adapt ed toengage the body, said body member having means engaging the free ends ofsaid spring.

l2. In a grease cup, the combination oi' a body having vertical grooveson the interior, a cap threaded on the body having openings in its topand a spring having two legs and a connecting portion, lugs extendingfrom the connecting portion through the openings in the cap and beingupset at the top of the cap, wing members carried by each leg andextending around and having two parallel portions engaging the sides oifthe other leg, said legs at their lower ends engaging the grooves in thebody portion.

In testimony whereof, I hereunto a'liix my signature in the presence oftwo witnesses.
